Warnings
Black Box Warnings
In short-term studies, antidepressants increased risk of suicidal thinking and behavior in children, adolescents, and young (<24 years) adults taking antidepressants for major depressive disorders and other psychiatric illnesses
This increase was not seen in patients aged >24 years; slight decrease in suicidal thinking was seen in adults aged >65 years
In children and young adults, risks must be weighed against benefits of taking antidepressants
Patients should be monitored closely for changes in behavior, clinical worsening, and suicidal tendencies; this should be done during initial 1-2 months of therapy and dosage adjustments
Patient’s family should communicate any abrupt behavioral changes to healthcare provider
Worsening behavior and suicidal tendencies that are not part of presenting symptoms may necessitate discontinuance of therapy
Drug is not approved for use in pediatric patients
Contraindications
Concomitant use of monoamine oxidase inhibitors (MAOIs), use of MAOIs within 5 days after discontinuance of milnacipran, or initiation of milnacipran within 14 days after discontinuance of MAOIs
Patients being treated with linezolid or intravenous methylene blue
Cautions
Milnacipran is serotonin-norepinephrine reuptake inhibitor (SNRI) similar to those used for depression and other psychiatric disorders; monitoring and close observation for clinical worsening, suicidality, and unusual changes in behavior are necessary, especially during first few months of treatment and when dosage is increased or decreased (see Black Box Warnings)
Potentially life-threatening serotonin syndrome has been reported with both SNRIs and selective serotonin reuptake inhibitors (SSRIs) when these agents are taken alone, but especially when they are coadministered with other serotonergic agents; thus, patient medications should be thoroughly reviewed for other serotonergic drugs (eg, tryptophan supplements, tramadol, serotonin agonists [triptans], MAOIs, tricyclic antidepressants [TCAs], SSRIs, methylene blue, meperidine, methadone, buspirone, amphetamines, linezolid); serotonin syndrome can also occur when these drugs are used alone
May increase blood pressure (BP) or heart rate (HR); BP should be controlled before initiation of milnacipran; BP and HR should be monitored while patient is taking drug; consider dose reduction or discontinuation of therapy in patients with sustained hypertension or tachycardia during therapy
SSRIs and SNRIs may impair platelet aggregation and increase the risk of bleeding events, ranging from ecchymoses, hematomas, epistaxis, petechiae, and GI hemorrhage to life-threatening hemorrhage; concomitant use of aspirin, NSAIDs, warfarin, other anticoagulants, or other drugs known to affect platelet function may add to this risk; inform patients about increased risk of bleeding associated with concomitant use with NSAIDs, aspirin, or other drugs that affect coagulation
Neonates exposed to SNRIs or SSRIs late in third trimester are at risk for complications such as feeding difficulties, irritability, and respiratory problems
Prescription should be written for smallest amount consistent with good patient care; alert family members to monitor for emergence of suicidality, including panic attacks, hostility, irritability, insomnia, anxiety, agitation, mania and hypomania
Bone fracture reported with antidepressant treatment; consider possibility of fracture in patients that present with unexplained bone pain, swelling, or bruising
Use caution in patients with history of seizures
Moderate renal impairment
Avoid use in severe hepatic impairment; discontinue therapy with signs of hepatic dysfunction or jaundice; do not reinitiate therapy unless another source or cause identified
Avoid concomitant use in patients with substantial alcohol use or chronic liver disease
Withdrawal symptoms reported in patients when discontinuing treatment; gradual dose reduction recommended
Pupillary dilation that occurs following use of SNRI drugs including milnacipran may trigger angle closure attack in patients with anatomically narrow angles who do not have a patent iridectomy; for patients who have not had an iridectomy for narrow-angle glaucoma risk factors, consider performing evaluation
Patietns with history of obstructive uropathies may experience higher rates of genitourinary adverse drug reactions (ADRs)
ESRD: Use not recommended
Development of SIADH and hyponatremia reported with SSRIs and SNRIs, predominantly in the elderly; volume depletion and/or concurrent use of diuretics may increase risk
May cause urinary hesitance; advise patients to report urinary symptoms or difficulties; use caution in patients with history of lower urinary tract disorders, including benign prostatic hyperplasia or prostatitis
May worsen psychosis in patients with mood disorders; a shift to mania or hypomania reported with bipolar disorder; avoid monotherapy in patients with bipolar disorder; screen prospective patients for bipolar disorder when presenting with depressive symptoms
Sexual dysfunction
- In female patients, SSRI/SNRI use may result in decreased libido and delayed or absent orgasm
- Important for prescribers to inquire about sexual function prior to initiation of therapy and to inquire specifically about changes in sexual function during treatment, because sexual function may not be spontaneously reported
- When evaluating changes in sexual function, obtaining a detailed history (including timing of symptom onset) is important because sexual symptoms may have other causes, including underlying psychiatric disorder
- Discuss potential management strategies to support patients in making informed decisions about treatment
Pregnancy & Lactation
Pregnancy
There is a pregnancy exposure registry that monitors pregnancy outcomes in women exposed to this drug during pregnancy
Physicians are advised to recommend that pregnant patients taking SAVELLA enroll in the Savella Pregnancy Registry; enrollment is voluntary and may be initiated by pregnant patients or their healthcare providers by contacting the registry at 1-877-643-3010 or by email at pregnancyregistries@incresearch.com; data forms may also be downloaded from the registry website at www.savellapregnancyregistry.com
Based on data from published observational studies, exposure to SSRIs, particularly in the month before delivery, has been associated with < 2-fold increase in risk of postpartum hemorrhage
The available data on use in pregnant women are insufficient to evaluate for a drug-associated risk of major birth defects, miscarriage, or adverse maternal or fetal outcomes; there are risks associated with exposure to serotonin and norepinephrine reuptake inhibitors (SNRIs) and selective serotonin reuptake inhibitors (SSRIs); including this drug, during pregnancy
Animal data
- Animal reproduction studies have been performed in rats, rabbits and mice; this drug was shown to increase embryofetal and perinatal lethality in rats and the incidence of a minor skeletal variation in rabbits at doses below (rat) or approximately equal to(rabbit) the maximum recommended human dose (MRHD) of 200 mg/day on a mg/m2 basis; no effects were seen in mice when treated with milnacipran during the period of organogenesis at doses up to 3 times MHRD on a mg/m2 basis
- Therapy in the month before delivery may be associated with an increased risk of postpartum hemorrhage
- Neonates exposed to SNRIs or SSRIs, including this drug, late in the third trimester have developed complications requiring prolonged hospitalization, respiratory support, and tube feeding
- Such complications can arise immediately upon delivery; reported clinical findings have included respiratory distress, cyanosis, apnea, seizures, temperature instability, feeding difficulty, vomiting, hypoglycemia, hypotonia, hypertonia, hyperreflexia, tremor, jitteriness, irritability, and constant crying
- These findings are consistent with either direct toxic effect of SSRIs and SNRIs or possibly, a drug discontinuation syndrome; it should be noted that, in some cases, the clinical picture is consistent with serotonin syndrome
Lactation
This drug is present in human milk; there are no reports on effects of therapy on the breastfed child and on milk production/excretion
However, there are reports of agitation, irritability, poor feeding, and poor weight gain in infants exposed to SSRIs or SNRIsthrough breast milk
The developmental and health benefits of breastfeeding should be considered along with mother’s clinical need for therapy and any potential adverse effects on breastfed child from this drug or from underlying maternal conditions
Monitor infants exposed to this drug for agitation, irritability, poor feeding and poor weight gain
Pregnancy Categories
A: Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.
B: May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk. C: Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done. D: Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk. X: Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist. NA: Information not available.Pharmacology

MILNACIPRAN - ORAL
(mil-NA-si-pran)
COMMON BRAND NAME(S): Savella
WARNING: Although not used for depression, this medication is in the same class as antidepressant medications. Antidepressant medications are used to treat a variety of conditions, including depression and other mental/mood disorders. These medications can help prevent suicidal thoughts/attempts and provide other important benefits. However, studies have shown that a small number of people (especially people younger than 25) who take antidepressants for any condition may experience worsening depression, other mental/mood symptoms, or suicidal thoughts/attempts. It is very important to talk with the doctor about the risks and benefits of antidepressant medication (especially for people younger than 25), even if treatment is not for a mental/mood condition.Tell the doctor right away if you notice worsening depression/other psychiatric conditions, unusual behavior changes (including possible suicidal thoughts/attempts), or other mental/mood changes (including new/worsening anxiety, panic attacks, trouble sleeping, irritability, hostile/angry feelings, impulsive actions, severe restlessness, very rapid speech). Be especially watchful for these symptoms when a new antidepressant is started or when the dose is changed.
USES: Milnacipran is used to treat pain caused by a condition called fibromyalgia that affects the muscles, tendons, ligaments, and supporting tissues.This medication is a serotonin-norepinephrine reuptake inhibitor (SNRI) that works by helping to restore the balance of certain natural substances in the brain (neurotransmitters).
HOW TO USE: Read the Medication Guide provided by your pharmacist before you start using milnacipran and each time you get a refill. If you have any questions, consult your doctor or pharmacist.Take this medication by mouth with or without food as directed by your doctor, usually 2 times a day. If you have nausea, it may help to take this medication with food.Dosage is based on your medical condition and response to treatment.To reduce your risk of side effects, your doctor may start you at a low dose and gradually increase your dose. Follow your doctor's instructions carefully. Do not increase your dose or take this medication more often than prescribed. Your condition will not improve any faster, and the risk of serious side effects may be increased.If you suddenly stop using this medication, you may have withdrawal symptoms (such as mood swings, headache, tiredness, sleep changes, brief feelings similar to electric shock). To help prevent withdrawal, your doctor may lower your dose slowly. Withdrawal is more likely if you have used milnacipran for a long time or in high doses. Tell your doctor or pharmacist right away if you have withdrawal.Tell your doctor if your condition does not improve or if it worsens.
SIDE EFFECTS: See also Warning section.Nausea, vomiting, dry mouth, constipation, loss of appetite, dizziness, increased sweating, headache, or hot flashes (flushing) may occur. If any of these effects last or get worse, tell your doctor promptly.Remember that this medication has been prescribed because your doctor has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.This medication may raise your blood pressure. Check your blood pressure regularly and tell your doctor if the results are high.Tell your doctor right away if you have any serious side effects, including: fast/pounding heartbeat, changes in sexual ability, decreased interest in sex, painful/difficult urination, seizures, yellowing eyes/skin, dark urine, severe stomach/abdominal pain, easy bleeding/bruising.Get medical help right away if you have any very serious side effects, including: black stools, vomit that looks like coffee grounds, eye pain/swelling/redness, widened pupils, vision changes (such as seeing rainbows around lights at night, blurred vision).This medication may increase serotonin and rarely cause a very serious condition called serotonin syndrome/toxicity. The risk increases if you are also taking other drugs that increase serotonin, so tell your doctor or pharmacist of all the drugs you take (see Drug Interactions section). Get medical help right away if you develop some of the following symptoms: fast heartbeat, hallucinations, loss of coordination, severe dizziness, severe nausea/vomiting/diarrhea, twitching muscles, unexplained fever, unusual agitation/restlessness.A very serious allergic reaction to this drug is rare. However, get medical help right away if you notice any symptoms of a serious allergic reaction, including: rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing.This is not a complete list of possible side effects. If you notice other effects not listed above, contact your doctor or pharmacist.In the US -Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088 or at www.fda.gov/medwatch.In Canada - Call your doctor for medical advice about side effects. You may report side effects to Health Canada at 1-866-234-2345.
PRECAUTIONS: Before taking milnacipran, tell your doctor or pharmacist if you are allergic to it; or to levomilnacipran; or if you have any other allergies. This product may contain inactive ingredients, which can cause allergic reactions or other problems. Talk to your pharmacist for more details.Before using this medication, tell your doctor or pharmacist your medical history, especially of: kidney disease, liver disease, alcohol use, personal or family history of glaucoma (angle-closure type), personal or family history of psychiatric disorders (such as bipolar/manic-depressive disorder), personal or family history of suicide attempts, high blood pressure, heart problems (such as chest pain, heart attack, fast/irregular heartbeat), seizure disorder, dehydration, intestinal ulcers/bleeding (peptic ulcer disease), mineral imbalance (low level of sodium in the blood), painful/difficult urination (for example, due to enlarged prostate).This drug may make you dizzy. Alcohol or marijuana (cannabis) can make you more dizzy. Do not drive, use machinery, or do anything that needs alertness until you can do it safely. Avoid alcoholic beverages. Talk to your doctor if you are using marijuana (cannabis). Drinking alcohol can also increase your risk of liver problems.Before having surgery, tell your doctor or dentist about all the products you use (including prescription drugs, nonprescription drugs, and herbal products).Older adults may be more sensitive to the side effects of this drug, especially bleeding. Older adults may also be at greater risk for mineral imbalance (low level of sodium in the blood) while using this drug, especially if they are also taking "water pills" (diuretics) with this medication.During pregnancy, this medication should be used only when clearly needed. Discuss the risks and benefits with your doctor. Babies born to mothers who have used this drug during the last 3 months of pregnancy may rarely develop withdrawal symptoms such as feeding/breathing difficulties, seizures, muscle stiffness, or constant crying. If you notice any of these symptoms in your newborn, tell the doctor promptly.This medication passes into breast milk. Consult your doctor before breast-feeding.
DRUG INTERACTIONS: Drug interactions may change how your medications work or increase your risk for serious side effects. This document does not contain all possible drug interactions. Keep a list of all the products you use (including prescription/nonprescription drugs and herbal products) and share it with your doctor and pharmacist. Do not start, stop, or change the dosage of any medicines without your doctor's approval.Some products that may interact with this drug are: "water pills" (diuretics such as furosemide), other drugs that can cause bleeding/bruising (including antiplatelet drugs such as clopidogrel, NSAIDs such as ibuprofen/naproxen, "blood thinners" such as dabigatran/warfarin).Taking MAO inhibitors with this medication may cause a serious (possibly fatal) drug interaction. Avoid taking MAO inhibitors (isocarboxazid, linezolid, metaxalone, methylene blue, moclobemide, phenelzine, procarbazine, rasagiline, safinamide, selegiline, tranylcypromine) during treatment with this medication. Most MAO inhibitors should also not be taken for two weeks before and at least 5 days after treatment with this medication. Ask your doctor when to start or stop taking this medication.Aspirin can increase the risk of bleeding when used with this medication. However, if your doctor has directed you to take low-dose aspirin for heart attack or stroke prevention (usually 81-162 milligrams a day), you should continue taking it unless your doctor instructs you otherwise. Ask your doctor or pharmacist for more details.The risk of serotonin syndrome/toxicity increases if you are also taking other drugs that increase serotonin. Examples include street drugs such as MDMA/"ecstasy," St. John's wort, certain antidepressants (including SSRIs such as fluoxetine/paroxetine, other SNRIs such as duloxetine/venlafaxine), tryptophan, among others. The risk of serotonin syndrome/toxicity may be more likely when you start or increase the dose of these drugs.Milnacipran is very similar to levomilnacipran. Do not use medications containing levomilnacipran while using milnacipran.
OVERDOSE: If someone has overdosed and has serious symptoms such as passing out or trouble breathing, call 911. Otherwise, call a poison control center right away. US residents can call their local poison control center at 1-800-222-1222. Canada residents can call a provincial poison control center. Symptoms of overdose may include: confusion, severe drowsiness/dizziness.
